cabinets/pc enclosures/monobloc cabinets Stainless steel cabinets are for use in both corrosive and food processing environments. Areta has been manufactured in stainless steel without changing its design structure or its accessories, thus providing all the benefits offered by the standard painted version. The range includes also the stainless steel pc enclosures and the monobloc cabinets with the same technical features of the ones in mild steel.
boxes Stainless steel boxes are manufactured using the same construction and productive concepts of the ST and STP mild steel range. Standard components are also in stainless steel including hinges, screws and the locking cam. The clean external finish gives the product an aestheticallly very pleasant and highly professional appearance. Boxes are placed in a Polythene bag and heavy-duty carton with clear identification labels.
terminal boxes For use in corrosive and food processing environments, these stainless steel terminal boxes offer the same benefits as the stainless steel boxes. The clean external finish gives the product an aesthetically very pleasant and highly professional appearance.
control desks Stainless steel control desks, both monobloc or modular, are provided with the same technical features of the ones in mild steel.
features at a glance • 304 grade stainless steel. 316 also available • IP 65 protection. Cabinets IP 55 • compatible accessories with mild steel range • high quality brushed finish • modifications available on short lead times.

introduction stainless steel A highly corrosion resistance iron-based alloy containing between 18% and 20% chromium. Stainless steel is the strongest of the corrosion resistance materials. It exhibits many of the same resistances attributed to Fibreglass materials as well as resistance to polar solvents such as acetone. Generally 2 grades of stainless steel are available dependant on the application and environment the enclosures are to be placed. Grade 304 is the most common and is suitable for environments such as food processing or in general wet areas where a degree of corrosion resistance is required. Grade 316 material has a higher content of nickel and is generally used for highly corrosive environments such as off-shore or petro-chemical plants. Various elements of the materials are: Austenic steel: Fe + Cr (16÷28%) + Ni (6÷32%) + C (0.02÷0.1%) Ferritic steel: Fe + Cr (10.5÷30%) + C (0.02÷0.1%) Martensitic steel: Fe + Cr (12÷19%) + C (0.08÷1.2%) ETA manufactures from grade 304, offered as the standard, and the more resistant AISI316, manufactured on request. AISI304 and AISI316: chemical and physical characteristics. Grade 304 and 316 are both austenitic, with chrome percentage more than 16% and nickel percentage more than 6%. In the below table are listed the main chemical and physical characteristics of austenitic steel.

ETA manufacturing cycle of stainless steel products ETA manufacturing process of stainless steel product follows a strict quality system to ensure optimum product quality is achieved. The various manufacturing processes which are constantly being reviewed and up-graded include: a) laser cutting operation, achieved by using high-tech precision machinery b) folding operation, achieved by using specific tools c) welding operation, achieved by using TIG technology in inert atmosphere that allows minimal heat generation around the welded area d) grinding, polishing operation and rounding of the edges, in order to obtain a uniform and clean surface and to avoid sharp edges e) gasket positioning operation, fully automated, maximises IP rating f) brushing operation, made by automatic process that allows for clean, even surfaces typical for hygiene requirements. As 304 is the most common grade of steel used, 120 grit level is the most popular grain finish. Other grades, e.g. 230, can be provided on request. Panels of stainless steel floor standing cabinets are pre-stained and supplied with a PVC covering to protect the material during handling g) assembling: the product is finally packed in plastic bags and then into a heavy-duty carton to provide protection during transportation.

reliable performance even at temperatures below zero, due to its properties of high toughness and plasticity stainless steel keeps its mechanical characteristics for a period 3 times more than mild steel. Consequently it allows to avoid additional surface treatments like painting or plating
recommended for applications in seismic areas
no additional maintenance is required, other than cleaning stainless steel is structurally stronger than mild steel no deterioration when exposed to sunlight can be fully earthed, unlike insulated enclosures
stainless steel enclosures are easily EMC shielded
